I have written this guide about modern commemorative half dollars in order to dispel and correct the very high number of errors and misrepresentations that I see on eBay.  I will detail all US Modern Halves in this guide and provide mintages and metal composition data for each of them.  As you will see, virtually all of the half dollars are cupronickel.  I have highlighted the 3 Silver Half Dollar Commemoratives below:
